37th time lucky

Monfils made two major quarter-finals in a season for the first time in his career, having already advanced that far at the French Open.

Dimitrov broke through to his first grand slam semifinal at Wimbledon but couldn't follow that up with another deep run.

In an entertaining match, both players made unbelievable gets, including Monfils' shot in the final game that he nearly curled around the net. Dimitrov got it back to win the point. But the match came down to break points: Monfils converted three of four, Dimitrov just one of seven.

Monfils moves on to play the winner of the night match between second-seeded Roger Federer and No.17-seeded Roberto Bautista Agut of Spain.

In other men's matches with a spot in the final eight at stake, sixth-seeded Tomas Berdych meets Dominic Thiem, and No. 14-seeded Marin Cilic plays 26th-seeded Gilles Simon.
